FILILINGI-REPLIENISHING MECHANISM FOR Looms.

SPECIFICATION forming part of LettersPatent No. 769,210, dated September 6, 1904. v Application filed \Tune 8, 1904. Serial No. 211,593 (No model.) i

To all whom it may concern:

Be it known that I, BELVIA J. DOBBINS, a citizen of the United States, and a' resident of Ninetysix, county of Greenwood, State of South Carolina, have invented an Improvement in Filling-Replenishing' Mechanism for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This inventionrelates more particularly to filling-replenishing, mechanism of looms of the Northrop type, such as forms the subjectrnat'ter of United States PatentNo. 529,940;

and it'has for its object the production of a simple, durable, and effective guide-support and buffer to cooperate with a filling-carrier or bobbin as it is transferred from the fillingfeeder to the shuttle.

Figure 1 is a side elevation and partial transverse section of a part of a filling-replenishing mechanism of the type referred to with one embodiment of. my invention applied thereto. Fig. 2 is an enlarged cross-sectional detail on the line 2 2, Fig. 1, the buffer being shown in elevation; and Fig. 3 is an inner face view, also enlarged, of the stand of the filling-feeder, showing the controlling-spring for the buffer. i Y

The lay A shuttle S, breast-beam A having secured to it a stand A on which is mountedthe filling-feeder, (only one of the disks a thereof being shown,) thetransferrer f, the means to actuate it to transfer singly the filling-carriers or bobbins b from the feeder to the shuttle, and the means for intermittingly rotating the feeder may be all substantially as in United States; Patent No. 664,7 90. As in said patent, an abutment h on the stand A serves to direct or guide one side of the head of a filling-carrier during transfer, the abutment forming a fixed side of a discharge-throat leading. from the feeder to the shuttlewhen the lay is in its forward position on front center.

Referring to Fig. 2, I have shown the inner face of the stand A as provided with a lateral hub 1 below the circular flange (0 Fig. 1, near 3, parallel to the axis-of the feeder.

its lower end and opposite the abutment la, the hub and thickened portion 2 of the stand forming an elongated rigid bearing for a stud On its outer endthe stud is provided with a broad, flat, or plate-like extension A, substantially at right angles thereto'towa'rd the abutment, said extension constituting the movable guidesupport or bufier. Theinner end of the stud has coiled around it astout spring 5,.one end thereof being upturned at 6 and hooked around a lug a on the stand A said lug preferably having a notch 25 to receive the wire, while the other end ofthe spring is hooked at 7 around a pin 8 on the stud. The spring is so wound as to normally maintain the buffer 4 in the position shown, said abutment extendingebelow the flange a toward the abutment h and projecting part way into the path of a filling-carrier when transferred.

At time of transfer the filling-carrier presses against the buffer, which yields and swings downward against the stress of the spring 5, and it acts upon the adjacent side of the head of the filling-carrier, guiding and supporting the same as it 'is moved down through the discharge-throat, When the transferrer f rises after a transfer, the spring 5 causes the buffer to return'to normal position in readiness for the next transferring operation.

The buffer audits studare strong and durable and cheap to construct, audit is applied and held in place, as well ascontrolled, by the spring without any bolts, screws, or other fastening devices, it-being manifest from an inspection of Fig. 2that the spring performs the double function of controller and retaining device for the buffer.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isw 1. An intermittingly-movable feeder to hold a plurality of filling-carriers, a stand on which it is mounted, an elongated bearing-hub on and integral with the stand at one side of the path of movement of a filling-carrier when transferred, a transferrer, a stud mounted to rock in the bearing-hub and having a rigidlyconnected buffer to yieldingly support and guide a filling-carrier when transferred, the

inner end of the stud projecting beyond the its other end with the stand, the spring be- 'tween its ends being coiled around the stud projecting beyond the hub, to control the angular movement of the stud and retain it in place in the bearing-hub.

2. Filling replenishing mechanism for looms, including an intermittingly-rotatable I feeder to hold a series of circularly-arranged filling-carriers, a stand on which it is mounted, a transferrer, an abutment extended into the path of the filling-carrier next to be transferred, a stud with which the buffer is rigidly connected, a pin on the opposite end of the stud, abearing-hub on the stand and in which the stud is mounted to rock, the inner end of the stud projecting beyond the end of the hub, a coiled spring surrounding the projecting end of the stud, and connected at one end with said pin on the stud, and a lug on the stand near the bearing-hub, the opposite end of the spring being hooked around the lug and fixedly held thereby, the spring acting to hub and prevent its longitudinal movement.

3. An intermittingly-movable feeder to hold a plurality of filling-carriers, a stand in which it is mounted, a fixed abutment on the stand to form one side of a discharge-throat through which the filling-carriers pass, an elongated bearing-hub on the stand opposite the abutment, at lug on the stand near and parallel to the hub, a stud mounted to rock in said hub and projecting at both ends beyond it, a spring surrounding one end of the stud adjacent the hub and secured at one of its ends directly to the stud, the other end of the spring being detachably secured to the lug and fixed] y held thereby, and a buffer rigidly connected with the opposite end of the stud forming a yield-
